FASTENING-INSERTING MACHINE.

To all whom it may concern:

Be it known that we, ARTHUR ERNEST JEnnAM and JosErH GonLDBoURN,subjects of the King of England, residing at Leicester, Leicestershi e,England, have invented certain Improvements in Fastening-InsertingMachines, of which the following description, in connection with theaccompanying d 'awings, is a specificationflike reference characters onthe drawings indicating like parts in the several figures.

This invention relates to machines for inserting fastenings. By Way ofillustration the invention is herein'shown as embodied in a machine ofthe type disclosed in United States Letters Patent No.5t90,621, granted.January 9A, 1893, on an application of Louis Goddu, for inserting screwthreaded fastenings in the soles of boots and shoes.

In the use of machines of the general type disclosed in said LettersPatent on some classes of work, the maximum spacing desired exceedsconsiderably the maximum spacing obtainable with machines of this typeas these machines have been constructed heretofore, Also, it isfrequently desired to make considerable changes in the spacing of thefastenings at different parts of a given shoe. Consequently, in suchcases, it has been necessary for the operator to ad Vance the workmanually between successive fastening locations, depending necessarilyupon his own skill and accuracy to effect the different spacingsproperly and to locate the fastenings correctly, with the resultnot'onlytha t especial skill has been re quired on the part of theoperator and the operators work has been rendered considerably morelaborious, but the output of the machine has been reduced considerablyand the results obtained have generally been unsatisfactory.

One of the objects of the present invention is to eliminate thesedisadvantages by producing an improved fastening inserting machineespecially adapted for inserting screw threaded fastenings in the solesof boots and shoes, which machine may readily be rendered capable ofdealing either with any ordinary and normal spacings or with spacingsconsiderably outside of the normal range of spacings.

A further and more particular object of the invention is to provide animproved fas Specification of Letters Patent. Application filed July 26,1916. Serial No. 111,527.

ratemea is. so, rare.

tening inserting machine of this general type so constructed as topermit a change from normal to extra wide spacing to: be made at thewill of the operator without interrupting the operation of the machineto provide for effecting any desired changes of spacing during theoperation upon a given shoe without necessitating either stopping themachine or rendering necessary a second series of operations upon thatshoe to insert the extra widely spaced fastenings after the normallyspaced fastenings have been inserted.

In accordance with these and other objects of the invention, theillustrated machine is provided with novel manually controlled meanscapable of initiation by the operator at any stage in the operationsofthe machine, which means are so constructed and arranged that wheneverextra Wide spacings are desired the operation of the fastening insertingmechanism may be suspended periodically Withoutsuspending or interferingwith the operation of the work feeding mechanism, to the end that theamount ofv work feeding movement between successive fastening insertlngoperations may be doubled, thereby doubling the spacing range of I themachine.

Preferably, and as shown, the illustrated means for periodicallysuspending the op eration of the fastening inserting mechanism isorganized to not automatically at regular intervals during the operationof the machine, the construction and arrangement being such that theinitial suspension of operation of the fastening inserting mechanismwill invariably occur at a predetermined point in the cycle ofoperations of the machine regardless of when the operator actuates themeans for suspending the operation of this mechanism. As herein shown,this result is accomplished by automatically suspending the operation-ofthe fastening inserting mechanism at a predetermined time between eachtwo fastening inserting operations, so that, as long as extra widespacing is desired, the work feeding mechanism will impart to the worktwo work feeding steps between every two successive fastening insertingoperations.

These and other objects and features of the present invention will beapparentfrom the following detailed description of a maautomatic chineof the above mentioned type having a preferred embodiment of the presentin vention incorporated therein, and the novel features of the inventionare defined in the appended claims.

Referring to the drawings,

Figure 1 is a side elevation of the upper portion of the machine; and

Fig. 2 is front elevation partly in section, showing certain parts ofthe upper portion of the machine of Fig. 1 on a somewhat larger scale.

The machine in which the present invention is herein shown asincorporated is substantially the same as that disclosed in said abovementioned Letters Patent except as hereinafter set forth, and referencema be had to said Letters Patent for a more de tailed description of theconstruction and operation of certain parts not fully described herein.

The machine has a base carrying a column 2 which supports a head 4having mounted. therein a vertically disposed spindle 6 which carriesthe screw threaded wire from which the fastenings are formed. Thespindle 6 is continuously rotated by a belt passing over a pulley 8 onthe upper end of the spindle and over idlers 10 to a driving pulley (notshown) in the base of the machine arranged to be clutched to acontinuously running pulley operated from a source of power. The spindle6 is provided with a worm which engages worm gears 20 (Fig. 1.) upon theforward ends of parallel shafts, one of which is indicated at 22, thisshaft 22 carrying the various cams for effecting the wire feeding, wiresevering, work feeding, and horn depressing movements. These cams areeach formed to cause two operations of the parts operated thereby duringeachcomplete revolution of the cam shaft 22.

The wire is fed downwardly through the spindle 6 by a wire feeding andinserting sleeve 2 1 surrounding the spindle 6 and slidably mounted inguideways in the ma chine frame, the lower end of said sleeve beingprovided with wire gripping members 26 which operate intermittently toseize the wire as said sleeve is moved downwardly. The sleeve 24 isreciprocated in the machine frame to feed successive lengths of wire andinsert them in the work by a wire feed lever 28 (Fig. 2) pivoted at 30to the machine frame and having two forwardly pro jecting arms 31 (Figs.1 and 2) each carrying a segmental gear 32, the gears 32 engagingrespectively racks 34 formed on a yoke attached to the upper end of thesleeve 24. An upwardly extending arm 36 (Fig. 2) of the lever 28 carriesa cam roll 38 operatively engaged by a wire feeding edge cam $0 on thecam shaft 22. A wire feed lever 28 is normally held in position to beoperated by the cam 10 to move the wire feeding sleeve 2% downwardly bya comparatively strong spring (not shown) the lower part of which bearsagainst a part of the lever 28.

After a proper length of wire has been inserted in the work, the wire issevered by wire severing knives mounted in the lower ends of two knifecarrying arms 41-1 and e13 both fulcrumed on a shaft 4:7 mounted in themachine frame. The knife carrying arms or holders 11 and d3 carry gears(not shown) which mesh with coeperating gears on the forward end of ashaft 51 (Fig. 1). Upon rocking movement of the shaft 51, the holders 41and 13 are reciprocated toward and from each other to cause the cuttingedges of the knives to sever successive lengths of wire intimed relationto the operation of the wire feeding mechanism. The shaft 51 isoscillated through connections to a wire severing cam 4.5 provided withtwo outstanding toes one of which is shown at 53 and a daptcd to operateintermittently a lever 49 operatively connected to the shaft 51.

In the use of the machine the shoe to be operated upon is mounted upon ahorn (not shown) and clamped between the horn and an abutment indicatedat In order that each wire fastening inserted in the work may correspondto the thickness of the work at the fastening location, the extent offeeding movement imparted to the wire feed lever 28 by the wire feedingcam 40 is automatically varied. This is effected by providing the hornwith a laterally extending arm (not shown) to the outer end of which isattached a measuring rod or leg 59 (Fig. 2) projecting upwardly througha guide in the machine frame and adapted upon upward movement of saidrod to engage and more upwardly a cooperating rod 61, the lower end ofwhich is in line with, but normally spaced from, the upper end of therod The rod 61 has its upper end pivotally secured to the end of arearwardly extending arm 63 of the wire feed lever 28. lVhenevcr thehorn is moved upwardly into work clamping position. the measuring rod55) is correspondingly moved to engage and move the cooperating rod 61,whereupon the wire feed lever 28 is adjusted in respect to its operatingcam 40 according to the thickness of the work.

After each fastening has been inserted and cut off, the work isautomatically fed by a feed wheel 12r- (Fig. 1). The feed wheel 127carries on its under side a. bevel gear indicated at 123 meshing with abevel gear 125 on the outer end of a shaft 129. The opposite end of theshaft 129 carries loosely a toothed sleeve 131 adapted to be oscillatedby a rack 139 (Fig. 2) on the lower end of one arm of a two-armed lever133. The other arm 141 of this lever has a stud and slot adjustableconnection inditends to force the rod 50 downwardly and operates torestore the lever 52 to normal position after movement thereof againstthe pressure of the'spring 66.

In the illustrated machine, as in the machine of said Letters Patent No.$0,621, the operating cam d0 for the wire feed mechanism, like the Wirecutting mechanism cam 4:5, is a double throw cam so constructed thatduring every revolution of the cam shaft 22 two operative movements 7 ofthe wire feeding mechanism areeffected. The present invention providesmeans for automatically and periodically swinging the lever 52 once inevery revolution of the cam shaft 22 whenever said meansis operative,thus throwing over the latch 56 and setting the switch 58 to suspend theoperation of the wire feeding mechanism once in every revolution of thecam shaft so that, when extra wide spacing is desired, every alternateWire feeding movement will be omitted automatically and, instead offeeding and inserting two fastenings during each revolution of the camshaft, the machine will insert one fastening onlyduring each revolutionof the cam shaft.

Inasmuch as the described means for periodically suspending theoperation of the wire feeding mechanism is independent of, and doesnotinterfere With, the operation of the work feeding mechanism, it will beseen that, whenever the said means is operative, the work will haveimparted to it tWo feeding steps or movements between each two fasteninginserting operations, thereby exactly doubling the spacingcapacity ofthe machine. As shown, the means for thus automatically and periodicallyswinging the lever 52 independently of the trea'dle rod 50 to effectalternate-suspension of the operation of the wire feeding mechanismcomprises a double armed leverpivoted on the machine frame on anextension ofthe shaft which carries the wire feed arm 31, which doublearmed lever carries on one arm 68 a roll 70 adapted to be engaged by anedge cam piece 72 fitted on the wire feed operating cam 40 and operatingto swing the double armed lever once in every revolution of the camshaft. The other arm 74 of the double armed lever is pivotally connectedto one end of a rod or plunger 76, the other end of which rod isarranged to be received in a recess 78 (Fig. .2) at one side of thelever 52. A spring 80 Fig. 1) connected at one end to the machine frameand at the other end to the rod 76 acts both to force the rod 76laterally in line with the recess 78 and also in the direction tomaintain the roll 7 0 in contact with the edge piece 72 on the cam 40.Located in supports in the machine frame at one side of the rod 76 is arotatable shaft indicated at 82 (Fig. 1) carrying a cam 84 so locatedthat rotating of the shaft 82 displaces the rod 7 6 laterally againstits spring 80 out of line with the recess 78 so that, in thereciprocation of the rod 76 by en g ment of the edge cam piece 72 withthe roll 70 on the double armed lever, the rod 70 does not enter therecess 78.

The rotatable shaft 82 is designed to be provided with connections to aknee lever or treadle (not shown) by movement of which the operator mayrotate the said shaft at will during the operation of the machine tocause the lever 52 to be operated to move the latch 56 and set theswitch 58 periodically once in every revolution of the cam shaft 22 tosuspend the operation of the wire feeding mechanism.

In the use of the illustrated machine, the operator, in commencingoperations upon a given piece of work, depresses the treadle whichoperates the treadle rod 50, thereby through the lever 52 and springblade 5 L positioning the latch 56 to set the switch 58 to render thewire feeding and cutting mechanisms and the horn raising and (lepressingmechanisms operative. If normal spacing is desired, the knee lover ortreadle controlling the periodic suspension of the Wire feedingmechanism is set to position the shaft 82 so as to displace the rod 76laterally out of line with the recess 78 in the lever 52. Whenever extrawide spacing of the fastenings is desired, the operator moves the saidknee lever or treadle oppositely to rotate the shaft 82 so that the rod76 will be positioned by its spring 80 in line with the recess 78 in thelever 52 whereupon, once in every revolution of the cam shaft 22, thelever 52 will be moved to set the latch 56 to operate the switch 58 inthe direction to force the wedge shaped block 60 into operative relationto the rod (31, thereby forcing the cam roll 38 on the upward extension36 of the wire feed lever 28 out of the path of movement of the cam 40and, at the same time, through the connections above described,rendering the wire cutting mechanism inoperative. So long as the rockshaft 82 and the rod 76 are so positioned, the Wire feeding mechanismwill operate once only in every revolution of the cam shaft 22, andconsequently only one wire feeding movement will be effected for everytwo work feeding movements.

It will be noted that the operation of the illustrated embodiment of theinvention is entirely positive, with the result that maintenance ofaccurate time relationship of the parts of the control mechanismrelatively to the other operating mechanisms of the machine is assured.

Although the invention is herein shown and described as embodied in amachine of the type set forth in said Letters Patent No.
